Hi

My chinese made clone does not retain time, date or settings.

Can someone please confirm that it should work and is not some FW bug.

What could be broken or missing?

Is this probably a fault in the HackRF or Portapack?

Thanks
Vitor

I found out what the problem was:

The HackRF One used with the Portapack has a shield around the RF part. This shield is exactly opposite to the backup battery.

When looking closely I noticed that the pins that hold the (+) side of the Lithium battery were touching the shield, thus short-circuiting the battery and causing the memory loss.

By bending the pins over the battery, this was fixed and the HackRF One + Portapack are correctly retaining settings and RTC time+date.

I leave this solution for fellow users with the same problem. It is down to the Lithium battery cell holder, which comes with unbended pins.

Regards,
Vitor

Thanks. I had noticed this with mine, but didn't have the time to dig into it.
Which portapack do you have?
